In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 650 Gigabyte OC 1GB Edition are massively better than the AMD Radeon X1900 Series.

The GTX 650 was released over three years more recently than the Radeon X1900 Series, and so the GTX 650 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon X1900 Series when running the latest games.

The GTX 650 has 768 MB more video memory than the Radeon X1900 Series, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 650 also has superior memory performance overall.

The GTX 650 has 16 GB/sec greater memory bandwidth than the Radeon X1900 Series, which means that the memory performance of the GTX 650 is slightly better than the Radeon X1900 Series.

The GeForce GTX 650 Gigabyte OC 1GB Edition has 384 Shader Processing Units and the Radeon X1900 Series has 36. However, the actual shader performance of the GTX 650 is 426 and the actual shader performance of the Radeon X1900 Series is 13. The GTX 650 having 413 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 650 delivers a significantly smoother and more efficient experience when processing graphical data than the Radeon X1900 Series.

We would recommend a PSU with at least 400 Watts for the GTX 650 and a PSU with at least 520 Watts for the Radeon X1900 Series. The Radeon X1900 Series has been recommended a PSU with 120 Watts more than the GTX 650. The difference is significant enough that the Radeon X1900 Series may have an adverse affect on your yearly electricity bills in comparison to the GTX 650.

GPU Mini Review

Mini ReviewGeForce GTX 650 Gigabyte OC 1GB Edition is a special edition of the fast-middle-class GeForce GTX 650 1GB.
This special edition comes overclocked out of the box to 1110MHz and features a custom-designed 10 cm cooler.
Benchmarks indicate a 4% performance boost when compared to the reference card and so this GPU is suitable for medium to high settings on most demanding games but not with extreme resolutions.
Radeon X1900 Series is not a GPU but instead a combination between Radeon X1900 GT, Radeon X1900 XT and Radeon X1900 XTX whose rank is a balance between the three and that exists for System Requirements purposes only.
